Starting the watch
Your MARINE watch is a self-winding mechanical
English
watch. When first starting your watch, we recommend
winding the watch manually to reach a certain portion
of the reserve, and then the self-winding system will
complete the power reserve while you are wearing the
watch.
Crown X into position X1. This position makes it possible
to manually wind the movement.
Before manipulating the watch, if it is stopped, wind the
crown 30 times by turning the crown upwards . Then,
the watch worn on the wrist winds up and reaches its
full autonomy automatically. When unworn, following
a complete winding, the watch will stop after about
38 hours.
